Althoug most of the brazilian public zoos still need a few changes on a few structures, we can't let to notice how they changed in the last decades, Once the animal welfare (or animal welness) is a concept that fortunately gained a lot of space in the modern times.Here I'm posting a "before and after" of Belo Horizonte zoo, state of Minas Gerais, Brazil. Obs: All the pictures in my posts are from my authory, but the old pictures are from the zoo's archive, wich were and exposed in the zoo's 60th birthday last year, and I photographed these pictures. 1 - Aquatic birds lake - (first pic - 1980, second and third pics - 2019; nowadays it is named japanese garden and displays a few swan and koi fish species) 2 Elephant house and exhibit - (first pic - 1969, second and third pics - 2019) The exhibit improved two times it's size and got a new sleeping area for the three african elephants that now live there. 3 - Big cat exhibits - (First pic - 1979, second pic - 2019) probably the most drastic change. For many years the big cats lived in very small cages, untill a big renovation in the 80's, wich brought 1300 square meters habitats for lions, tigers, jaguars and pumas. Even though the present exhibits don't have the most natural aspect in the world, they have enough space and structures that the animals need. 4 - Bird plaza - (First pic - 1980, second and third pics - 2019) There's much more to compare... the topic has reached the limit of 10 pics, so, please, tell me if you want more pictures of this one and more brazilian zoos comparisson from the old structures and now. Hope you enjoy the big transformations!
